 ABSTRACT

A study was conducted to evaluate the effect of non-genetic factors on birth weight, weaning weight and growth performance in Kilakarsal sheep. A period of five years data of Kilakarsal lambs born between 2010 and 2014 at Livestock Farm Complex, Veterinary College and Research Institute, Tirunelveli, Tamil Nadu were utilized for analysis. The average birth weight was 2.682 ± 0.04  and 2.498 ± 0.05 kg respectively for male and female of season I (September – January) lambs and 2.539 ± 0.04 and 2.350 ± 0.05 kg respectively for male and female lambs born during season II (March – July). From the results, it was observed that the season of lambing has significant influence (P<0.05) on birth weight of lambs. Similarly, sex of the lambs also had a highly significant (P<0.01) influence on birth weight and male had a higher birth weight irrespective of the season of birth. However, sex and season of birth had no influence on weaning weight and average daily gain at pre-weaning period. Whereas, sex of the lambs had an influence on post weaning and overall average daily weight gain.
